An atmospheric river brought additional rain, strong winds, and flooding to the Bay Area Tuesday, with an increasing chance of thunderstorms later in the afternoon.

The Bay Area weather forecast has more rain and wind as another atmospheric river arrives and flood evacuations are issued along the Russian River.

Heavy rain is hitting the Bay Area and coastal areas this week as an atmospheric river moves through Northern California.

In Sonoma County, Green Valley Creek at Martinelli Road has reached a moderate flood stage, and the Russian River at Guerneville is expected to have minor flooding by Wednesday morning. Flooding in the North Bay is expected to continue throughout the day, the weather service said.

The National Weather Service said this week's atmospheric river is proving to be stronger than initially expected.

Heavy precipitation is falling mostly in mountain areas. A flood watch in also in effect for the coast of central California, including the San Francisco Bay Area and Sacramento Valley.

Days after an atmospheric river brought record-setting rainfall to California, the state is in the crosshairs of another rainy storm system.
